Beneficial mutations are more frequently fixed in large populations than in small ones, whereas deleterious mutations are more frequently eliminated.
Explanation:
Answer:
This question is asking to formulate a hypothesis for the experiment in the question. A hypothesis is:
IF natural compost is used instead of artificial fertilizer, THEN the tomato plants will grow faster and taller than when artificial fertilizer was used.
Explanation:
In an experiment, a hypothesis is formulated to provide a possible explanation or solution to an observed problem or question. The hypothesis must be testable or falsifiable via an experimentation.
In this experiment involving a biology student who is trying to find out if using natural compost will cause his tomato plants to grow faster and taller than his previously used artificial fertilizer. A possible hypothesis for this experiment goes thus:
IF natural compost is used instead of artificial fertilizer, THEN the tomato plants will grow faster and taller than when artificial fertilizer was used.
Answer:
A cell is defined as the structural and functional unit of an organism.
The average size of the prokaryotic cell lies between 0.1 to 10 micrometers whereas the average size of the eukaryotic cell is approximately 25 micrometers.
Four things are found in all the cells: genetic material (either DNA or RNA), cell membrane, cytoplasm, and the ribosome.
All the living cells grow and reproduce (sexually or asexually) and have the ability to respond to stimuli.
Thus, characteristics of a cell may include: cell grows and reproduces, responds to stimuli, contains DNA or RNA, not both , and contains a cell membrane.
Answer:
-During citric acid cycle or Krebs cycle, radioactive carbon will be first appear in citric acid
Explanation:
During cellular respiration, glucose is first converted into pyruvate molecules by the process of glycolysis. These pyruvate molecules go for oxidative decarboxylation, during which acetyl co-enzyme A (acetyl CoA) is formed along with removal of carbon dioxide.
The acetyl co-enzyme enters to the next step in cellular respiration or citric acid cycle or Krebs cycle. The first step of citric acid cycle is formation of citric acid by joining of acetyl CoA and oxaloacetate.
As citric acid is first molecule formed during citric acid cycle, radioactive carbon would be first appear in citric acid.
<span>Bariatric surgery is a surgery created to help one lose weight. The set-point theory says that the body’s regulatory controls help a person maintain a specific body weight as time goes on. Bariatric surgery works to establish a new set-point by altering body weight and establishing weight loss results.</span>
